7.7 Package Management Environment Variables
If the PLT_PKG_SSL_NO_VERIFY environment variable is set, server certificates are not validated for HTTPS connections. When accessing Git servers over HTTPS, GIT_SSL_NO_VERIFY must be set, too, to disable certificate validation.
As noted in the specification of GitHub-repository package sources, if the PLT_USE_GITHUB_API environment variable is set, GitHub packages are obtained using the GitHub API protocol instead of using the Git protocol.
